Tostudy the origin of the magnetic transition in BaVS₃, wemeasured the dc magnetization on La_0.1Ba_0.9VS₃ sintered samples near theferromagnetic transition. Effective critical exponents and amplitudes are obtained bymeans of standard modified Arrot plots and the Kouvel-Fisher method,while asymptotic critical exponents and amplitudes are obtained by meansof "correction to scaling" analysis. The two methods yield similarresults, but the latter is superior with respect to theachieved uncertainty. The obtained results indicate that the universality classof magnetic interactions driving the transition changes from short tolong range when cooling through T_c.
